All capitalized terms used herein which are not otherwise defined herein have the same meanings given to such terms in the Original Schedule 13D, as amended.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby amended to include the following:

The amount of funds used by the WP X Funds to purchase the shares of Series A-3 Preferred as described in this Amendment No. 8 was furnished from the working capital of such WP X Funds. The total amount of funds paid by the WP X Funds to purchase the securities of the Company purchased on January 11, 2013 as described in this Amendment No. 8 was $5,400,000.

Item 4. Purpose of the Transaction

Item 4 of the Schedule 13D is hereby amended to include the following:

On January 11, 2013, pursuant to the terms of the 2012 Investment Agreement (as amended by the 2012 Purchase Agreement Amendment), (i) WP X purchased 52,326 shares of the Company’s Series A-3 Preferred for an aggregate purchase price of $5,232,600 and (ii) WPP X purchased 1,674 shares of Series A-3 Preferred for an aggregate purchase price of $167,400.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

All of the computations and share amounts used herein do not give effect to any accretion on the shares of Series A-1 Preferred, Series A-2 Preferred or Series A-3 Preferred after January 11, 2013. The percentages used herein are calculated based upon the 22,001,891 shares of Common Stock outstanding as of November 13, 2012 as reported in the Company’s Quarterly Report on Form 10-Q  for the quarterly period ended September 30, 2012 filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on November 14, 2012. The number of shares of Common Stock that may be deemed to be beneficially owned by the Warburg Pincus Reporting Persons, and the percentage of the outstanding shares represented thereby, in each case as reported in this Schedule 13D, are based on the number of shares of Common Stock issuable to the Warburg Pincus Reporting Persons upon conversion of the shares of Series A-1 Preferred, Series A-2 Preferred and Series A-3 Preferred owned by the Warburg Pincus Reporting Persons on January 11, 2013 and the number of shares of Common Stock issuable to the Warburg Pincus Reporting Persons upon conversion of the remaining 420,000 shares of Series A-3 Preferred which the WP X Funds have the right to acquire pursuant to the 2012 Investment Agreement (without giving effect to the

11

right of the Deerfield Purchasers to purchase ten percent (10%) of such shares of Series A-3 Preferred, which exercise would reduce the number of shares acquirable by the WP X Funds).  On January 11, 2013, the Deerfield Purchasers exercised their right to purchase ten percent (10%) of the shares of Series A-3 Preferred acquired pursuant to the 2012 Investment Agreement and acquired 6,000 shares of Series A-3 Preferred in the aggregate, which reduced the number of shares acquirable by the WP X Funds pursuant to their contractual right by such amount.

(b)WP X is the direct beneficial owner of 359,797 shares of Series A-1 Preferred, 95,931 shares of Series A-2 Preferred and 563,958 shares of Series A-3 Preferred (comprised of 156,978 shares of Series A-3 Preferred presently outstanding and 406,980 shares of Series A-3 Preferred which WP X has the right to acquire). As of January 11, 2013, such shares are, in the aggregate, convertible into 257,336,352 shares of Common Stock (assuming such shares of Series A-3 Preferred which WP X has the right to acquire are issued), representing approximately 89.5% of the outstanding shares of Common Stock. 

WPP X is the direct beneficial owner of 11,510 shares of Series A-1 Preferred, 3,069 shares of Series A-2 Preferred and 18,042 shares of Series A-3 Preferred (comprised of 5,022 shares of Series A-3 Preferred presently outstanding and 13,020 shares of Series A-3 Preferred which WPP X has the right to acquire). As of January 11, 2013, such shares are, in the aggregate, convertible into 8,232,545 shares of Common Stock (assuming such shares of Series A-3 Preferred which WPP X has the right to acquire are issued), representing approximately 2.9% of the outstanding shares of Common Stock. 

Due to their respective relationships with the WP X Funds and each other, as of January 11, 2013, each of the Warburg Pincus Reporting Persons may be deemed to beneficially own shares of Common Stock by virtue of their beneficial ownership of shares of Series A-1 Preferred, Series A-2 Preferred and Series A-3 Preferred. Assuming the full conversion of the Series A-1 Preferred in accordance with the terms of the Series A-1 Certificate, the full conversion of the Series A-2 Preferred in accordance with the terms of the Series A-2 Certificate, and the full conversion of the Series A-3 Preferred in accordance with the terms of the Series A-3 Certificate, the Warburg Pincus Reporting Persons may be deemed to beneficially own 265,568,897 shares of Common Stock, representing approximately 92.4% of the outstanding class of Common Stock, based on a total of 287,570,788 shares of Common Stock, which is comprised of: (i) the 22,001,891shares of Common Stock outstanding referenced above, (ii) the 62,133,098shares of Common Stock issuable to WP X and WPP X upon the conversion of shares of Series A-1 Preferred described above, (iii) the 36,099,990 shares of Common Stock issuable to WP X and WPP X upon the conversion of  shares of Series A-2 Preferred described above and (iv) the 167,335,809 shares of Common Stock issuable to WP X and WPP X upon the conversion of shares of Series A-3 Preferred (including the shares of Series A-3 Preferred which the WP X Funds have the right to acquire pursuant to the 2012 Investment Agreement (without giving effect to the right of the Deerfield Purchasers to purchase ten percent (10%) of such shares of Series A-3 Preferred, which exercise would reduce the number of shares acquirable by the WP X Funds)).

(c)Each of WP X, WPP X, WP X LP, WP X LLC, WPP LLC, WP LLC and WP may be deemed to share with the WP X Funds the power to (i) dispose or to direct the disposition and (ii) vote or direct the vote of the 265,568,897shares of Common Stock the WP X Funds may be deemed to beneficially own (and convert into) as of January 11, 2013.

Charles R. Kaye and Joseph P. Landy are the Managing General Partners of WP and the Managing Members and Co−Presidents of WP LLC and may be deemed to control the other Warburg Pincus Reporting Persons. Messrs. Kaye and Landy disclaim beneficial ownership of all shares held by the WP X Funds. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person or any of its affiliates, other than the WP X Funds, is the beneficial owner of any shares of Common Stock for purposes of Section 13(d) of the Exchange Act, as amended, or for any other purpose.

(d)Other than as set forth in this Schedule 13D, during the last sixty (60) days there were no transactions in the Common Stock effected by the Warburg Pincus Reporting Persons, nor, to the best of their knowledge, by any of their directors, executive officers, general partners or members.

(e)Not applicable.

(f)Not applicable.
